No, this is not another article about tree rings, hockey sticks, and rewritten history, although that is one tree in the climate forest.
A group of scientists dismissed historical evidence and misled the public about temperature trends. Some dismiss their actions as bad science, but the evidence, particularly exposed in the leaked e-mails from the Climatic Research Unit (CRU), indicate differently. Many, including those claiming to be climate scientists were misled because they were experts on another tree in another part of the forest. The Intergovernmental Panel on Climate Change (IPCC) is not studying climatology, but specialists looking at some very limited components of an extremely complex system.
We live in a generalized world in an age of specialization. These problems are manifesting themselves more and more as the world systems break down into increasingly small pieces. It used to be there were general rules with exceptions to the rule – now everything is an exception. The problem is evident in the misuse of specialized knowledge by climate scientists. Using tree rings as representing temperature is a classic example.
